SHUTTER ATTACHMENT FUR DOORS.

Application led March 13, 1922. Serial No. 543,374.

To all 'zo/10m 'it 'may concern.'

Be it known that I, LYDIA MARIAN OI-IAR- Row, a. citizen of Ythe UnitedStates, and a resident I' Philadelphia, in the county of Philadelphiaand State vof Pennsylvania.,

have invented a new and useful Improvement in Shutter Attachments forDoors, of which the following is a full, clear, and exact description.

My invention'relates to improvements in a vcnti-lating attachment fordoors, and Yit consists in the combinations, constructions andarrangements hereinV described and claimed.

An object of my invention is to provide a device of the characterdescribed by means of which a door may be held `partially opened toprovide ventilation which prevents persons from entering the room fromthe outside.

A further object of my invention is to provide a device of the characterdescribed which may be folded and secured clear of the door when not inuse. n

A further object of my invention is to provide a device of the characterdescribed which is simple in construction, easy to operate andthoroughly practical commercially.

Other objects and advantages will appear in the following specification.and the novel features of the invention will be particularly pointed outin the appended claims.

My invention i5 illustrated in the accompanying drawings, forming partof this application, in which- Fig. 1 is a view of an embodiment of myinvention with a Ventilating attachment in an inoperative position,

F ig. 2 is a view of the mechanism illustrated in Fig. 1, showing theventilating attachment in use,

Fig. 3 is a pla-n view of the Ventilating attachment to show the detailsof construction,

In carrying out my invention, I make use of three sheet metalventilating shutters 1, 2 and 3. which are hingedly connected to oneanother by means of integral hinge fastenings 4 and 5.

The ventilating shutters are each pro-vided with louvers 6, which arearranged to open upwardly so that one cannot see through the shuttersfrom either side. The shutter 1 is constructed so that it is narrowerthan the shutters 2 and 3 for the purpose hereinafter described'.

F our hingedly mounted supporting plates 'T are disposed at the outeredge of the shutter 3 and are secured by means of wood f screws 9 to theframe 10 of the door l11. Each of the plates 7 is provided withl anoutwardly extending eye 12. The eyes 12 are 'in exact registration withelongated -openings 13 in the shutters 1, 2 and 3 so that when theshuttersl 1, 2 and 3 arefyfolded against the plates .7, the eyes-12`will 'project through the openings 13. A relatively narrow metal plate14 is hingedly mounted l at 15 to the outer edge'ot the shutter 1 and isalso provided with openings 13 in registration with the eyes k12. 'Y

Each of the plates 7l is provided Vwith a bolt 16 loosely attached tothe plate g by means'of the chain 17.r The chain 17 is Voi' suilicientlength to permit the bolt `16to be passed through the eyes 12 after theshutters and the plate 14 are folded thereagainst, thus locking theshutters and the plate 14 in `an inoperative position adjacent the doorframe 10.

Means for removably securing the plate 14 to the edge of the door whenopen, is provided in a plurality of small metal buttons 18 secured tothe edge of the door and arranged for registration with the openings 13in the plate 14.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. My invention isparticularly well suited for use in hotels andsometimes where onedesires a maximum ventilation in the sleeping room, but where theopening of the door for this purpose may be inconvenient. In using mydevice, it would be merely necessary to release the bolt 16 from theeyes 12 when the device is in an inoperative position and to unfold theshutters. The plate 14 is then secured to the edge of the portion bypassing the buttons 18 through the openings 1,3

and turning the huttons'so that they will prevent the removing of theplate 14 by pressure thereagainst, as from the outside. The passage ofair to or from the room is hereupon established, Vsince the air may passthrough the louvers 6 of the shutters and .also through the opening 19between the iframe 10 and the door 11 at the top thereof.

The door 11 may be moved toward and away from the frame 10 to vary theopening therebetween without removing the plate Fi, e. g

14 from the edge of the door. TWhen a ventilating attaohnienttliusdescribed is not in use, the shu'ttersgl, 2 and aretfolfdedbaelr upontheplates 7 and the plate le is folder against the shutter l so that theeyes I2 p'i'otrude through -t'le 'openings 1S jot'theinter-z posedshutters and plate and the bolts 16 are passed through the eyes 'l2 v:tolookv the-iattachment in its inoperative position.

I claim:

l. The combination with a 'hingedly inounted door and a traine for saiddoor, of a tolda'ble Ventilating 'shutter comprising foldable sectionslh'in'gc'adly supported at one edge on said frame, said shutterV havinga plurality of plates hingedly mounted to -one another 'and providedwith ventila-ting openings therethrough, one of said plates beinghingedly supported at one edge on said trarne, and mea-ns for removablysecuring laf/asie the' opposite edge of said shutter to said door. i

The lconahination `with a hingedly mounted door and a frame for saiddoor, of a foldalole Ventilating shutterhingedly supported at 'one edgeonsafidvfraina a rela tively narrowV plate hingedly connected to fthe'oi'iterinost seotion .of said shutter, said f plate havingaplurality ot openings therethrough, and apl'urality of fastening buttonssecured to said door, said k-biittons being arranged to engage the:openings in'said .plate to lock said plate to said door. p

4. The combination with a hingedly mounted door and a traine for saiddoor, ol a foldable Ventilating shutter hin-gedly supported at one edgefon said traine, a relatively narrow plate hingedly oonnectedfto theoutermost section of said shut-ter, -sa-id lplate havinga plurality1 ofopenings there-Y:

through, and a lplurality of asteninghut- `tons secured to said door,said buttons being arranged to Lengagev the openings in said plate tolock said plate to said' door, and means for removably locking saidshutter and vplate 'against said frame when folded and in an inoperativeposition.
